I have recently come upon some comments about the much greater destructiveness of higher speed rounds versus the lower speed sounds - against hard inanimate objects. Against flesh - well known. But against objects. Does anyone have any good experience with this - any guidelines as to what you should or shouldn't be shooting at - depending on how you do or don't want to tear up a certain target. The comments were concerning favorite set up steel plate targets that were normally used for all kinds of different cartridges - mostly pistols (but some pretty big pistols in the mix) and some rifles. The high speed high power rounds were not used against some favorite steel targets - for fear of severely damaging them - and wanting them functionable later for other demonstrations. Any thoughts on this. I'm just not that knowledgeable... But I'd like to understand.
